og12 语法第33题，求高人解答，真心求教

33.    Because an oversupply of computer chips has sent
prices plunging, the manufacturer has announced that
it will cut production by closing its factories for two
days a month.

(A)    Because an oversupply of computer chips has
sent prices plunging,
(B)    Because of plunging prices for computer chips,
which is due to an oversupply,
(C)    Because computer chip prices have been sent
plunging, which resulted from an oversupply,
(D)    Due to plunging computer chip prices from an
oversupply,
(E)    Due to an oversupply, with the result that
computer chip prices have been sent plunging

对og解释不理解，选项A中 an oversupply后面的谓语怎么可以说是has sent prices plunging，供应过剩怎么可以价格下降，搞不懂。
C还有就是对C的解释，不理解啊。
求高手赐教。

先说为什么供应过剩会价格下降：
物以稀为贵嘛，卖东西的多了，卖家都想卖，自然只有降价吸引买家啦
再说C选项：
C是典型的错误，企图用which来指代之前描述的整件事情（chip降价这件事），而在GMAT语法中，只有as能起到指代之前的整套主谓结构的作用（所以用什么that，it等等都是错误的）。或者可以说，which指代不明
顺便把D和E也说了，due to根据prep语法笔记上说，不支持放在句首，因为是介宾短语作状语，需要保证状语的逻辑主语与主句主语一致，但是表示原因的状语很难做到这一点，所以due to放句首严格来说是错误的语法结构，但是我似乎记得有特例，忘记了。总之就是表原因优选because+从句

楼上，我觉得plunging在这里不是一个名词，而是一个现在分词。不知道我理解的对不对，欢迎大家拍砖。which怎么能修饰现在分词呢？

句子的意思是价格的下降，而如果认为which修饰plunging的话，只是单纯的解释下降，显然是不合理的，下降可以是任何一种下降嘛~
